CARPET OR THE LIKE MOUNTING FOR STAIRWAYS.

Specification of Letters Patent. Patented June 21, 1921.

Application filed March 6, 1920. Serial No. 363,821.

To all whom it may concern:

Be it known that I, CHARLES D. ARM- STRONG, a citizen of the United States, re siding at N o. 2l03 Harrison street, San Francisco, in the county of San Francisco and State of California, have invented a new and useful Carpet or the like Mounting for Stairways, of which the following is a specification.

My invention relates to means for mounting carpet or the like on stairways, and has reference more particularly to means, which for convenience I will refer to throughout the following description as a plate made to receive strips of the material to be mounted, and maintain them in fixed relation, relative to the steps to be covered.

The primary object of my invention is to provide a Simple and cheap means of repairing steps of stairways in which the carpet or the like covering thereof has become worn.

According to the preferred manner of reducing the invention to practice, the plate may be mounted on stepsand made to cover the worn out tread surface of the existing step coverings. The plate being so constructed as to mount a new tread surface in a more convenient and practical manner.

In connection with the accompanying drawing which forms a part of this description:

Figure 1 is a perspective view of a sec tion of steps illustrating the application of the invention;

Fig. 2 is a section of the step showing the invention as applied thereto; and

Fig. 8 is a detailed view in section of a step showing the relative position of the plate afi'ixed thereto.

Referring now to the drawing in detail, the plate 1 is preferably constructed of sheet metal and stamped with a relative long and wide depression 2 formed to receive the carpet or like strip and with a border 3 having perforations at spaced intervals to enable the plate to be mounted to the steps over the existing carpet covering, by means of screws, nails or the like 4. The nap of the existing carpet covering of the steps will be sufiicient to accommodate the depress1on 2 thus enabling the border of the plate to be conveniently aifixed by means of the set screws or the like to the step.

The plate may be made in any desirable size according to the area of the step to be covered by the material of the new tread surface. Further, in the case of Stairways where the steps turn to the right or left, the plate may be shaped to coincide with the triangular shape of the step at such points.

It is to be noted that the plate is so constructed that the carpet or the like may cover not only the top of the steps but also the front overhanging edge 5 and a portion of the riser 6.

In mounting the carpet or other material on the steps by means of the plate, I would prefer to use some cementing or the like compound which would be spread over the surface of the depression 2 with the carpet or like material in this manner cemented, so to speak, in the depression. The thickness of the depression may or may not coincide with the thickness of the covering material used.

To increase the adhesion of the material which is cemented in the depression, the top surface of the depression may be roughened and thus overcome any tendency of the 1naterial to become loosened.

In reducing the invention to practice and to best realize the commercial possibilities of the same, I would suggest that the plates be stamped, as above mentioned, from sheet material and offered to the trade as a practical manner of repairing worn stair covering without necessitating the removing of the old carpet or like covering from the steps.

I-wish it understood that I do not limit myself to a metal plate as the same may be made from fiber or other material. Fur thermore, while I have shown the plate as covering the width of the step, this need not be the case in every instance as it may be desirable to cover only the edge of the step with new material. Then again instead of securing the material to be mounted within the depression by adhesion, I reserve the right to rivet the same therein or in fact, fix it in any convenient manner.

I claimi l A device for renewing carpet or the like on thetreadsurface of steps including a thin plate made to overlie the tread of one step and the riser of anadjacent step, a depression in that portion of the plate
